Question

我从这个链接获得了天气预报应用程序的示例代码：

http://www.anddev.org/viewtopic.php?t=361

并尝试在模拟器上运行它但显示错误

我尝试了很多东西来解决它，但我不能

如何解决这个问题？

在这一行我得到了错误

xr.parse(new InputSource(url.openStream()));

这些是logcat消息

Answer 1

您可能遇到源XML编码问题。尝试将InputSource的编码设置为UTF8。这是一个例子：

    InputSource is = new InputSource(url.openStream());
    is.setEncoding("UTF-8");
    xr.parse(is);
